Siasconset, MA

ZIP code 02564 is assigned to Siasconset, MA, and falls within Nantucket County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 243 people live inside it.

At 40 residents per square mile spread over 6.069 square miles, 02564 reads as a rural area. It is a sparsely populated postal code, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.

Housing in 02564 costs far above the national median. A typical home is valued at $1,546,900 against a US median of $207,500. Ownership dominates: 91.5% of occupied homes are owner-occupied, which usually signals an established residential area with relatively low turnover.

The building stock is dominated by detached single-family houses, which account for 99.1% of housing units here. The median construction year is 1983, making the housing here from the later twentieth century. The vacancy rate of 92.5% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews considerably older than the national median, with a median age of 61.8 against 42 nationally. The average household holds 2.29 people, and 78.3% are family households.

Getting to work takes 19.0 minutes on average one way. The dominant mode is drove alone at 19.3% of workers, while 15.7% take public transit, 19.3% walk. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 02564 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.

For anyone weighing a move, 02564 offers a compact profile of Siasconset: 243 residents, 56.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 13.5%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.

One caution worth repeating: a postal code is not a neighbourhood. 02564 may cover parts of several distinct areas, and a single neighbourhood in Siasconset may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
